2.2 Operation with operator unit
2.2.1 Functions of the operator unit
The operator unit is used to make all settings and readouts required for operating the
controller. All entries made on the operator unit are transmitted to the controller where
they are handled and stored; the operator unit itself does not store any data.
Information for the user is generated by the controller and forwarded to the operator
unit where it is displayed.
2.2.2 Operating concept
On the software side, all setting and readout values are arranged as datapoints of the
menu tree. Using the operating elements, every datapoint can be selected, displayed or
set. All menus appear on the LCD as clear text.
The controller has several languages preprogrammed; when commissioning the plant,
the required language is to be activated. The Operating Instructions for the enduser are
included with the controller; they contain the languages with which the controller is
supplied.
